glsl: Generated masked write instead of vector array index for UBO lowering
When reading a column from a row-major matrix, we would slot the single
value read into the vector using an ir_dereference_array of the vector
with a constant index. This will (eventually) get optimized to a
masked-write, so just generate the masked write in the first place.
v2: Remove unused variable 'chan'. Suggested by Ken.
